Thermal Characteristics of Borehole Stability Drilling in Hot Dry Rock [PDF]
ACS Omega, 2021 Due to high temperature of formation and low temperature of the drilling fluid while drilling in the hot dry rock, thermal stress around the borehole is easy to appear. The thermal stress causes cracks in the borehole wall. In severe cases, the cracks caused borehole instability and lost-circulation.

Hot Dry Rock Geothermal Exploration in Australia [PDF]
ASEG Extended Abstracts, 2004 Hot dry rock (HDR) geothermal energy is obtained by circulating water between injection and production wells through hot subsurface rocks. The recovered hot water should be around 250°C for efficient electricity generation. South Australia has become a focus for HDR developments due to its exceptionally hot subsurface rocks.
